People commit unthinkable acts every day. Time and again, we grapple to understand what drives a person to do such terrible things. But what if all of the questions we're asking are wrong? What if the source of all evil is not a matter of what...but who? Today, we have the first trailer for The Bye Bye Man. Warning! This may be too terrifying to watch!

Acclaimed genre actor Doug Jones brings the truly terrifying The Bye Bye Man to life in this all-new horror experience. You may not immediately recognize his face, but the fan-favorite has appeared in such hit movies as Hellboy, Pan's Labyrinth, Fantastic Four: Rise of the Silver Surfer and most recently in Crimson Peak, along with numerous other movies currently in production. Here, he brings a new boogeyman to the screen that rivals anything seen in the past decade.

The rest of the ensemble cast is rounded up by Douglas Smith, Lucien Laviscount, Michael Trucco, Carrie-Anne Moss and Faye Dunaway. The movie is directed by Stacy Title, who returns to the horror genre a decade after directing the cult hit Snoop Dogg's Hood of Horror. The screenplay comes from Jonathan Penner based on a short story by Robert Damon Schneck.

'Don't think it. Don't Say it.' That's the ominous warning given to audiences before watching this latest footage. Please don't hold us accountable should you decided to watch the terrifying moments contained in the clip below. Yes, the evil behind man's most unspeakable acts does have a name. But please don't say it aloud in our presence!
